PUMP-HANDLE.

SPECIFICATION forming part of Letters Patent No. 476,082, dated May 31,1892. Application flied February 15, 1892. Serial No. 421,594. (Nomodel.)

To all whom it may concern:

L e it known that I, CHARLES A. SELLON, a4 citlzen of the United States,residing at -Pike,

` in the county of lVyoming and State of New while exerting therequisite leverage, may be adjusted to make any length of strokedesired, according to the option of the person using the same.

To this endit is the main obj ect of this invention to provide a deviceof this character which, while simply adjusted to meet t-he exigcncy ofthe case, at the saine time is simple in construction and avoids the useof unnecessary parts.

With these and many other objects in view, which will readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination, and arrangement of partshereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure l is a side elevation ot a pump andpump-handle connected thereto constructed in accordance with thisinvention. Fig. 2 is a detail perspective View of the pump-handle and aportion of the pivoted bearing standard connected therewith. Fig. 3 is adetail view of the slotted guide. i

Referring to the accompanying drawings, A represents a pump of ordinaryconstruction and supporting the guide-arm B, arising above the same, andreceiving the pump-rod C, reciprocating in said pump. Pivoted to thebase ot' the pump at D is the swinging bearing-standard E, workingthrough the slotted guide F, secured to the body of the pump andextending to one side of the same, and said standard projects above thetop of the pump and terminates in an upper bifurcated end G; whichreceives the adj ust-able pump-handle H, mounted therein, as will benoted. The said pump-handle terminates in a quadrantadjusting head I.The arc J of said quadrant is provided with a series of adjustingpertorations j and terminates at one end opposite to the terminal of thehandle portion proper in a short arm j,which is pivotally connected tothe pump-rod at 7'2 between the bearing of the arm G and the top of thepump. Pivoted to the center K ot the quadrant is the U adjusting-link L,which straddles the arc J ot the quadrant, and is adj usted thereoverand held in any position desired bymeans ot the pin l, passingtherethrough and any one ot` the series of perforationsj in said arc,whereby a long or short stroke is obtained, as desired. A pivotbolt Mpasses through the upper bifurcated end G of the swingingbearing-standard E and through thercircumerentially-adjustable link L ashort distance below the adjusting-pin Z and forms the fulcrum orpivotal point for the quadrant-head, which works in the upper bifurcatedend ofthe swinging bearing-standard E, which readily gives to themovement of the pump-handle. It will be readily seen that by moving thecircuinferentially-adjnstable clevis L toward the pump-rod and securingthe same in such position a comparatively short stroke may be obtained,whereby a woman or child may easily operate the same; and, on the otherhand, by adjusting the same away .rom the pump-rod a correspondinglylong` stroke may be had. Y When the handle proper is raised until theclevs L is in a line with the standard E, the weight ot' thequadrant-head and the pump-rod rests upon the pivot-bolt ot said clevsat the center K of the quadrant, which thus allows the adjusting-pin Zto be readily removed and the handle swung in any position desired,while said clevis is still vertical to make the requisite adjustment,according to the length of stroke desired.

Although it is illustrated and has been specificall y described that thepu nlp-handle terminates in a quadrant-head, nevertheless it will beapparent that any sector of a circle would accomplish precisely the samefunction as a quadrant-head, or one quarter of a circle. The bestadjustment is obtained by the use of a head of this size; but a sectorgreater or less than a quadrant may be as advantageously employed,varying, of course, at lthe option of the manufacturer and size of pumpto be operated.

It is now thought that the construction, op-

IOO

eration, and many advantages of the hereindescribed pump-handle areapparent Without further description.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. In a pump-handle, the combination, With the pum p-rod and an ad jaeent bearing-standard, ot' an adj ustahle pump-handle terminating in asector-head connected to said pu mprod, and aciroumferentially-adjustable link connected with said quadrant and saidbearing-standard, substantially as set forth.

2. In a pump-handle, the Combination, With the p u 1n p-rod and an adjaeent bearing-standard, of an adjustable pump-handle terminating in thesector-head, Connected at one end j ot' the are t0 said pumprod, and alink pivoted to the center of the quadrant and circumferentiallyadjustable over the are thereof and pivotally connected with saidstandard, substantially as set forth.

3. In a pump-handle, the combination, with the pump-rod, of an adjacentbearingzstandard pivoted at its lower end and terminating in an upperbifuroated end, an adjustable pump-handle terminating in aquadrant-head, Working in said bifurcated standard end, said head beingConnected at one end of the are to said pum p-rod and provided with aseries of peforations in the are thereof, a link pivoted to the centerof the quadrant and cireumferentially adjustable over the are, anadjusting-pin engaging the outer end of the link in any one of theseries of perforations,

. and a pivot-bolt passing through the bifureated end of said standardand the circumferentially-adjustable link, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature inthe presence of two Witnesses.
